Chicago HD shows part 76472-06A as $175.25 ($140.20 after discount) and same price for the Europe part listed above.
I ordered this CD ROM from Appalachian HD and it was $160 after the discount they gave me. Chicago HD is cheaper but would probably have cost me more to ship it than $20. It is backordered, but only by a couple of days. I have until August for it to come in so that I can take it with me when I PCS.
One good thing about a GPS in Europe is that it shows what direction you are heading. As I recall the roads do NOT list a direction, simply a town heading one way and a town heading another way. When they list big towns like Heidelberg and Frankfurt its not too bad but when they list small towns you have never heard of it is a 50/50 proposition which way to go. The built in GPS shows direction, so at least I will know if I am heading where I want to go.
